For whatever reason the Americans do it bigger and allegedly better - be it with a negative or positive effect.
As Tom of TomDispatch writes in pulling together some of Americas "records"...
"Hey, aren't we the most exceptional nation in history? George Bush and his pals thought so -- and they were in a great American tradition of exceptionalism. Of course, they were imagining us as the most exceptional empire in history (or maybe at the end of it), the ultimate New Rome. Anyway, explain this to me: Among all the exceptional things we claim to do, how come we never take credit for what may be the most exceptional of all, our success of successes, the thing that makes us uniquely ourselves on this war-ridden planet -- peddling more arms to Earthlings than anyone else in the neighborhood? Why do we hide this rare talent under a bushel? In the interest of shining a proud light on an under-rated national skill, I asked Frida Berrigan to return the United States to its rightful place in the Pantheon of arms-dealing nations."
Frida's "list" is not one to be proud of. Read it here.
